Location: 26 km north of Srinagar,
Baramulla district, Jammu & Kashmir
Area: Ahansar 17 ha; Waskursar 38 ha
Altitude: 1583 m
Biogeographical province: 2.39.12
Wetland type: 13
Description of site: The wetlands lie within the
floodplain of the Jhelum river about a kilometre away from each other. Wakursar
is comparatively larger and deeper than Ahansar. The maximum depth of Ahansar
Lake is 5 m and that of Waskursar is 6 m. Both the lakes are semi drainage
lakes with perennial outflow channels. Catchment area of the lakes comprise
elevated stretches of fan-shaped projections known as karewa which are mostly
horizontal beds of fine-grained sand, loam, and sandy clay with lenticular
bands of gravelly conglomerates. Waters of both the lakes are moderately clear.
The water temperature varies according to the climatic conditions. In summer,
the lakes develop weak stratification. The lake waters are alkaline and have
a high calcium content. This may be due to the lime-rich catchment which brings
a high calcium load along with storm waters
Climatic conditions: Average annual precipitation
varies from 620 mm to 764 mm. Maximum temperature is 25° C and minimum about
1.8° C
Principal vegetation: Both the lakes are overgrown
with different species of macrophytes. Along the silted regions, where water
depth is shallow, only a few emergent species such as Phragmites communis
and Juncus effusus arefound growing. The important floating-rooted species
in the lakes are Nymphoides peltata, Nelumbo nucifera, Potamogeton natans,
Nymphaea albs, and Trapa natans. The deepest parts are colonised by Ceratophyllum
Myriophyllum community. Other important species are Potamogeton lucens, P.
Crispus, P. Pucillus, Hydrilla verticillata, Najas graminea, and minor. In
both the lakes, the submerged species of vegetation cover more area than the
floating-rooted type. About 120 species of phytoplankton have been recorded,
representing the following families: Chlorophyceae, Bacilariophyceae, Cyanophyceae,
Dinophyceae, and Chrysophyceae
Land tenure: Surrounding fields and orchards are under private
ownership. The wetlands are state-owned
Land use: Fishing, especially for mirror carp. Agricultural
activities are carried out on the lake shores
Disturbances and threats: Both the lakes are under severe
stress due to biotic pressure, resulting in gradual eutrophication
Economic and social values: The lakes support locally important
fishing
Fauna: Known to be an important site for waterfowl although
no census seems to have been undertaken
Special floral values: None
